Quantum HL-01 Earphones silver

115,00 €
Quantum HL-01 earphones offer a perfectly balanced sound for all musical genres, from classical music to heavy metal, from the sounds of nature to the electronic rhythm.
Dual Driver technology ensures maximum clarity and sound definition, which cannot be achieved with traditional full-range speakers. The central part of the coaxial driver has a diameter of 7 mm and ensures a clear reproduction of the upper tones and a natural reproduction of the mid-range sounds. The 13 mm circular driver reproduces bass with unprecedented depth and exceptional precision in all low frequencies. The integrated crossover (frequency separator filter) ensures perfect coordination of the two transmitters.
This model was developed specifically for Apple products.
The Quantum HL-01 kit includes a hard case to protect the earphones with a compartment to store all the accessories you can carry with you.
